Patent number: 12030207Abstract: A pressure plate 12 has an upper surface 12a and a lower surface 12b. A blade die unit 16 for machining a workpiece by applying a pressure to a principal surface of the workpiece is arranged on the lower surface 12b. A face plate 24 has an upper surface 24a and a lower surface 24b, and is arranged such that the upper surface 24a faces the lower surface 12b with the blade die unit 16 interposed therebetween. An upper pressure roller 20 applies a pressure directed from the upper surface 12a side toward the lower surface 12b side of the pressure plate 12 to a portion of the upper surface 12a. A lower pressure roller 22 applies a pressure directed from the lower surface 24b side toward the upper surface 24a side of the face plate 24 to a portion of the lower surface 24b.Type: GrantFiled: October 29, 2020Date of Patent: July 9, 2024Assignees: SAKURA SEIKI CO., LTD., UCHIDA YOKO CO., LTD., UCHIDA YOKO GLOBAL CO., LTD.Inventors: Ippei Muramoto, Tomoki Takada

Patent number: 10308455Abstract: A guide member (14) has an upper surface assisting conveyance of workpieces (44) mounted on a table (12) and is arranged downstream of the table (12) in a workpiece conveyance direction. A belt drive mechanism (16) has pulleys (26a to 26d, 28a to 28b), and endless belts (32a to 32d) wound around these pulleys, and is arranged above the table (12) and the guide member (14) so as to stride over the table (12) and the guide member (14). A first opening portion is formed on a bottom portion of the belt drive mechanism (16) to generate an upward suction force. A second opening portion is formed on the upper surface of the guide member (14) to generate a downward suction force. A magnitude of the suction force generated in the first opening portion exceeds a magnitude of the suction force generated in the second opening portion.Type: GrantFiled: October 7, 2016Date of Patent: June 4, 2019Assignees: SAKURA SEIKI CO., LTD., UCHIDA YOKO CO., LTD., UCHIDA YOKO GLOBAL LIMITEDInventors: Ippei Muramoto, Toshimasa Endo
